It's easier to understand actually practicing than talking. With Bram's guidance, Catherine became more and more aware of her abilities. "One, I'm tired... Bram, does this way of moving really help?" Catherine asked Bram. "Of course it helps. It's hard to move this way, but if you get used to it, no one can beat you." Bram said. "Ho, really? Sounds like a lie..." Katherine asked. "It's not a lie. The ability of vampires and bats to sense is top notch, so I can't open my eyes. But I can move. Any attack is easily avoided as long as the blood flow can be sensed." Bram told Catherine. "I wonder if it will really work..." Catherine said. "You don't have to worry. The vampires of history were called undefeated because of this cause." Bram asked. "An invincible vampire... Vampires and demons... Bram, who's better at your sensing abilities or Dante's?" Catherine asked Bram. "That's better, of course, Master Catherine. Mr. Dante's sensing ability is not his own power, but the power of the devil's heart. If Master Catherine gets used to this way of moving, she should always be able to go beyond Mr. Dante." Bram said. "But it's hard to sense the flow of biological blood! You have to concentrate very much, very hard! I want to give up now, myself." Catherine complained. "I know it's hard to get used to, but if you want to be strong, you just have to be patient." Bram said. "If you say so much, I'll be patient. What do we practice next?" Katherine asked. "What does Master Catherine want to practice? I'll be with you for any workout." Bram said. "I want to practice my stay in the air! Are you okay?" "Katherine asked." If Master Catherine wants to practice that, practice a stay in the air. "Bram said.

"Actually, how do you do it?" Catherine asked Bram. "Use all the power, and jump." Bram said. Catherine jumped at all costs when she heard Bram's instructions. In the air, he said, "My jumping power is strong! Bram, what's next?" Catherine said. Gravity also exists in this world, Catherine can't stay in the air long. "Jump again in the air when you fall." Bram said. Catherine jumped again, as Bram said, when she could pull to gravity. "Like this! But it won't last long!" Catherine said. "This is the weakness of our stay in the air. If the user does not have enough strength, it will fall right off." Bram said. "I want! Very hard!" Catherine said. She doesn't want to fall out of the air, so she's jumping hard in the air.
